The total amount of pink fluorescence was only slightly greater in females than in males in both the juvenile (mean ± SE, Males: = 31.54 ± 2.04 mm; Females: 36.31 ± 2.51 mm) and the adult age-classes (Males: = 28.17 ± 1.91 mm; Females: 30.52 ± 1.12 mm), although a comparison of their frequency distributions showed marginally non-significant differences between sexes (age-classes pooled, D = 0.327, P = 0.062; Fig. 2B,D ).
